UNDERWATER ELECTRICAL GENERATOR FOR THE HARNESSING OF BIDIRECTIONAL FLOOD CURRENTS

摘要

Underwater electrical energy generator with a three-blade propeller for the harnessing of energy from the water in the direction of its axis, in both directions. The propeller drives an alternating current generator located in a central dome from which there extend three arms joined to floats which close the Y-shaped structure by means of tie beams. The assembly has neutral floatability and is set into position by means of an anchoring system with a set of buoys joined to the bottom by one or more cables. An end of the generator is joined to an anchoring line by means of a horizontal cable in one of the main directions of the current. From the other end another two horizontal cables, open at an angle with respect to the direction of the current, are joined to another two anchoring lines. The assembly can be ballasted to go from an operating vertical underwater position to a horizontal floating position to facilitate maintenance tasks.
